<p>PURPOSE:To prevent the generation of wrinkles by holding a plurality of sheets to a separated state by a guide part until said sheets are intoroduced into a cylindrical anvil. CONSTITUTION:A pin sonic member 5 is provided above a cylindrical anvil 4 in a freely vertically movable manner and the upper and lower guide rollers 6b, 6b constituting a guide part 6 are respectively provided to the sheet introducing part of a bonding apparatus 3 at upper and lower positions. The interval between the upper and lower guide rollers 6b, 6b is set so as to be slightly smaller than the diameter of the cylindrical anvil 4. Three kinds of sheets 1 are guided by rollers 6a and passed between the upper and lower guide rollers 6b, 6b in a mutually separated state to be introduced into the cylindrical anvil 4. These sheets are subjected to ultrasonic welding between the cylindrical anvil 4 and the pin sonic member 5 to be compounded and the laminated sheet is discharged to the outside by discharge rollers 8.</p> |
